Our verdict on Séance

Séance is a GTK4 terminal multiplexer for Linux users who run multiple AI coding-agent sessions. Its scrolling horizontal pane layout organizes terminal workspaces, while workspaces and tabs within columns provide a structure for separating projects or tasks. The software automatically detects supported agents and reports whether they are working, idle, or waiting for permission. It is open-source and free, with access through AppImage, Nix, Arch Linux, or source installation options.

Its standout feature is agent-aware session monitoring rather than general-purpose terminal management alone. Desktop notifications can surface permission requests and task completions, reducing the need to watch every pane continuously. Session persistence keeps workspaces available across restarts, and the command palette plus focus-follows-mouse support interactive navigation. For scripting and automation, Unix-socket control through seance ctl provides JSON output for control commands. Integrations include Claude Code, Codex, Pi, OpenCode, and Antigravity CLI.

Séance is a focused choice for Linux desktop users who want persistent, locally managed workspaces around AI coding agents. It supports Linux desktop environments using X11 or Wayland, as well as command-line access, and includes plugin and extension support. The trade-off is its narrow platform and collaboration scope: persistence is local, session sync is not included, and there are no collaboration features. Teams needing shared sessions or cross-device continuity should choose a different tool. Individual developers who primarily work on Linux and want agent status, notifications, and scripted control in one terminal environment should find Séance the more relevant fit.
